1112:   <filename(modulename)>: invalid group definition

     Explanation:  This message indicates that the file shown, which may
     be an .OBJ file or a .LIB file, contains an invalid object record.  If
     the file is expected to be valid, then it has probably become corrupt.

     Action:  Either recreate the file by recompiling, or reinstall the
     appropriate file from the installation disk.  For a CA-Clipper
     application, place EXTEND.LIB after CLIPPER.LIB in the link script, or
     do not mention these libraries, allowing them to be brought in by
     default in the correct order.
